Ryuk is a minimal, developer-first personal knowledge operating system engineered to organize bookmarks, notes, and technical references without bloated UI clutter.

Built as a high-performance Turborepo monorepo using Next.js 16 (App Router), Drizzle ORM, and PostgreSQL. Features categorised collections, instant search, and shareable public lists with secure tokens.

Includes an integrated API key management system designed to empower CLI tools and browser extensions to capture resources directly from terminal workflows.

Powered by Cheerio for automated metadata and OpenGraph scraping, Zustand for responsive client state, and TanStack Query for background synchronization.
